The short portion and the ground portion are formed an acute angle therebetween. The connection portion respectively connect a first radiating portion and a second radiating portion. The first radiating portion and the second radiating portion are parallel to said ground portion. The short portion is arranged between the ground portion and the first radiating portion. When the dual-band antenna operates at wireless operation, the connection portion, the first radiating portion and the second radiating portion resonate to obtain a first frequency range and a second frequency range.
